Bring your PC media and social networking programs to life by adding speakers to your computer setup. Adding speakers to your PC will allow you to play sound from movies as well as music, web clips and online telephone conversations. Whether you need to install a sound card or already have one, adding speakers to play sound on your home computer is a simple process that involves a few easy steps you can do on your own.
Install a sound card if you don't already have one in your computer. To install the card, shut the computer down, unplug it and open the case using a Phillips screwdriver. Depending on what type of case you have, the case may open on the left or on the right side.
Locate an open PCI slot and install the sound card according to the manufacturer's instructions. Close the case and plug the computer back in. Boot the computer and run the installation driver program for the sound card. You may need to reboot your PC to complete the installation process.

Locate the speaker plugs for your new sound card, usually located on the back panel of your PC. Plug the speakers into the corresponding jacks. Ensure that you have plugged each speaker into the correct jack for its placement in the stereo sound field. If the speakers are not self-powered, plug them in and power them on.
Run the setup program for your sound card to configure the PC speakers and identify your speaker setup type to your sound card driver program. Use the sound test in your sound card configuration utility to test each speaker to make sure it is working, correctly placed, and at a good volume.
